Determining location information using a location data point provided by a computing device

ABSTRACT

A system and method for determining location information using a location data point provided by a computing device is described. A location data point is received by a system from a client computing device. The system determines whether the location data point is within a predefined region from a plurality of predefined regions configured by a user of the system. If the location data point is within a predefined region, location information corresponding to the predefined region is transmitted to the client device. If the location data point is not within a predefined region, one or more third-party reverse geocoding services can be used that translates the location data point to a street address.

DETAILED DESCRIPTION

Examples described herein provide for a system that receives a locationdata point from a computing device and determines location informationcorresponding to that location data point for purposes of providinglocation-based services. In one example, the system can determine whichresource to use to determine the location information, based on whichresources are available or accessible by the system.

According to an example, the system can receive a location data point,such as a global positioning system (GPS) data point, from a clientcomputing device. The location data point can comprise a latitude, alongitude, and an error value. The system can perform a reversegeocoding process for the location data point to determine thecorresponding location information or address. In one example, thesystem can first determine whether the location data point is within apredefined region of a plurality of predefined regions that have beenconfigured by a user (e.g., an administrator) of the system. Theplurality of predefined regions can be stored, for example, in adatabase accessible by the system. If the location data point is withina predefined region, the location information corresponding to thepredefined region can be identified and transmitted to the clientdevice.

If the location data point is not within a predefined region, the systemcan determine whether a third-party reverse geocoding service isavailable or accessible for translating or converting the location datapoint to an address, such as a street address. In some examples, thesystem can communicate with a plurality of third-party reverse geocodingservices. If a third-party reverse geocoding service is accessible fortranslating the location data point to an address, the system cantransmit a request to the third-party reverse geocoding service, whichincludes the location data point, and can receive the correspondingaddress. The address can then be transmitted to the client device.

In some cases, the third-party reverse geocoding service(s) may not beavailable for or accessible by the system. In such situations, thesystem can determine whether a map database of the system (e.g., aninternal database maintained by the system) is available for translatingthe location data point to the address. If the map database isavailable, the system can retrieve a stored address from the mapdatabase using the location data point and transmit the retrievedaddress to the client device. If the map database is unavailable (or ifno address is found that corresponds to the location data point), thesystem can identify a specified text string to be transmitted to theclient device. In this manner, the system 100 can perform a reversegeocoding process based on a predetermined hierarchy or order.

Still further, the system can also receive a request for a transportservice from the client device. The request for transport can include alocation data point specified/selected by the user of the client device(e.g., either the previously transmitted location data point or a newlocation data point). The system can select a driver capable ofproviding the transport service based on the location data point of therequest for transport. According to some examples, the system candetermine whether the preferred language of the user of the clientdevice matches the preferred language of the selected driver. If thepreferred languages match, the system can transmit the determinedlocation information/address to the device of the driver. On the otherhand, if the preferred languages do not match, the system can performthe reverse geocoding process, e.g., on behalf of the driver, todetermine the location information or address in the preferred languageof the driver.

As used herein, a client device, a driver device, and/or a computingdevice refer to devices corresponding to desktop computers, cellulardevices or smartphones, personal digital assistants (PDAs), laptopcomputers, tablet devices, television (IP Television), etc., that canprovide network connectivity and processing resources for communicatingwith the system over a network. A driver device can also correspond toother devices of a transit object, or custom hardware, etc. The clientdevice and/or the driver device can also operate an applicationconfigured to communicate with the system.

Still further, the system, for example, can enable location-basedservices (such as a transportation service, a delivery service, anentertainment service) to be arranged between individuals using thecomputing devices described. As an example, a user can request anon-demand service, such as a transportation or delivery service (e.g.,food delivery, messenger service, food truck service, or productshipping) or an entertainment service (e.g., mariachi band, stringquartet), and the system can select a service provider, such as adriver, food provider, band, etc., that uses devices that communicatewith the system.

In still another example, multiple location data points are receivedover one or more networks, wherein the multiple location points arecommunicated from one or more client devices over a duration of time. Inresponse to receiving each of the multiple location data points, a datastore is accessed that includes a plurality of predefined geofences, inorder to determine whether that location data point is within apredefined region of any of the plurality of predefined geofences. Atleast one of the plurality of predefined geofences is configured by auser of the system. For at least one location data point that is notwithin a predefined region, (i) a determination is made as to anotherresource is to be used to provide location information to the clientdevice. One or more third-party reverse geocoding services are alsodetermined to translate the location data point. A request istransmitted to a third-party reverse geocoding service to translate eachof the multiple location data points to a street address, where therequest including the location data point. A corresponding streetaddress is received for each of the multiple location data points. Foreach of the multiple location data points, the corresponding streetaddress is transmitted to a client device that communicated the locationdata point.

System Description

FIG. 1 illustrates an example system to determine location informationusing a location data point, under an embodiment. In one example, thesystem can operate with or as part of another system that enablesservices to be arranged between parties (e.g., arrange a transportservice or a delivery service between a user and a service provider).For example, the system of FIG. 1 can correspond to a dispatch systemthat selects a driver for purpose of arranging a transport service for auser. The system 100 can receive a location data point from a clientdevice of the user and perform a reverse geocoding process to determinean address or other location information corresponding to the locationdata point.

Typically, a computing device can provide a location data point to athird-party reverse geocoding service and the third-party reversegeocoding service can perform a translation of the location data pointto a street address. However, there may be disadvantages for solelyusing a third-party reverse geocoding service to determine locationinformation. For example, third-party reverse geocoding service(s) canhave rate limits, such as a limited number of queries per second (QPS)allowed for a particular device, and/or can be costly. In situationswhere multiple client devices operate on the same network, such as on awireless local area network (WLAN), the third-party reverse geocodingservice can view the multiple devices querying the third-party reversegeocoding service as being the same device and lock out the devices(e.g., prevent the devices from making calls to the third-party reversegeocoding service). In addition, reliance on a particular third-partyreverse geocoding service may be problematic in some situations, such aswhen address data is inaccurate or when computing resources of thethird-party reverse geocoding service fail (e.g., server crash). Ratherthan enabling the client devices to directly transmit the location datapoint(s) to the third-party reverse geocoding services, the system 100of FIG. 1 can receive the location data point(s) from a client deviceand can perform a reverse geocoding process that may or may not utilizethe third-party reverse geocoding service(s).

According to an example, the system 100 includes a locationdetermination 110, a transport arrangement 120, a device interface 130,a service interface 140, a geofence database 150, a geofence interface155, and a map database 160. A plurality of client devices 170 and aplurality of driver devices 180 can communicate with the system 100 overone or more networks via the device interface 130. In some examples, thesystem 100 can also communicate with one or more third-party reversegeocoding services 190. The components of the system 100 can combine toreceive a location data point(s) from a client device 170 and perform areverse geocoding process to determine an address or locationinformation corresponding to the location data point(s). Logic can beimplemented with various applications (e.g., software) and/or withhardware of a computer system that implements the system 100.

Depending on implementation, one or more components of the system 100can be implemented on network side resources, such as on one or moreservers. The system 100 can also be implemented through other computersystems in alternative architectures (e.g., peer-to-peer networks,etc.). As an addition or an alternative, some or all of the componentsof the system 100 can be implemented on client devices 170, such asthrough applications that operate on the client devices 170 and/or thedriver devices 180. For example, a client application, such as a serviceapplication, can execute to perform one or more of the processesdescribed by the various components of the system 100. The system 100can communicate over a network, via a network interface (e.g.,wirelessly or using a wireline), to communicate with the one or moreclient devices 170 and the one or more driver devices 180.

The system 100 can communicate, over one or more networks, with clientdevices 170 and driver devices 180 using the device interface 130. Thedevice interface 130 can manage communications between the system 100and remote computing devices. In some examples, the client devices 170(and driver devices 180) can individually operate a service applicationthat can interface with the device interface 130 to communicate with thesystem 100. According to some examples, the applications can include oruse an application programming interface (API), such as an externallyfacing API, to communicate data with the device interface 130. Theexternally facing API can provide access to the system 100 via secureaccess channels over the network through any number of methods, such asweb-based forms, programmatic access via restful APIs, Simple ObjectAccess Protocol (SOAP), remote procedure call (RPC), scripting access,etc.

According to some examples, the location determination 110 can receive alocation data point 171 from a client device 170 via the deviceinterface 130. For example, when a user of a client device 170 operatesa service application, the user can interact with the user interface ofthe service application to select or specify a particular locationpertaining to the on-demand and/or location-based service. The user caninteract with a map interface, for example, which shows the user'scurrent location (e.g., the current location of the client device 170)as well as one or more graphic features (e.g., a pin) that can be movedon the map by the user to indicate a location for use with requesting alocation-based service. In one example, the location specified by thepin on the map can be a pick-up location and/or a destination locationfor a transport service, or a drop-off location for a delivery service.

When the user selects a location, e.g., by moving the pin on the mapinterface to a particular location, the client device 170 determines andtransmits a location data point 171 (corresponding to the particularlocation) to the system 100 via the device interface 130. According toexamples, the location data point 171 corresponding to the selectedlocation includes a latitude, a longitude, and an error value. Forexample, the client device 170 can include a global positioning system(GPS) component and/or other components that can determine the GPScoordinates for the current location of the client device 170 or theselected location on the map interface. The GPS component can alsoinclude an error value for the location data point 171 to indicate theaccuracy of the latitude and the longitude. For example, a location datapoint 171 with a high error value is deemed to be not as accurate as alocation data point 171 with a lower error value (e.g., the GPScomponent can have a high error for a location data point when, at thetime the GPS coordinates are determined, there is signal interference,hardware glitches, etc.).

According to one example, each time the user of the client device 170specifies a location on the map interface of the service application,such as a pick-up location for a transport service, the client device170 can provide the corresponding location data point 171 to the system100. For example, the user can select a first location on the mapinterface (e.g., move the pin via a finger touch on the touch-sensitivedisplay of the client device 170 and then remove the finger once thedesired location has been specified), and the client device 170 candetermine that the user has selected a location in response to the userremoving the finger from the touch-sensitive display and transmit acorresponding location data point 171 to the system 100. Immediatelythereafter (e.g., one second later), the user can select a differentsecond location on the map interface (e.g., the user decides that asecond location is better for transport service). Similarly, the clientdevice 170 can then transmit a location data point 171 corresponding tothe second location.

In some example, the user can continue to change the specified location(and cause the client device 170 to continue transmitting correspondinglocation data points 171) until (i) the user makes a transport request175 to the system 100, (ii) a predetermined time after the user made thetransport request 175, and/or (iii) the user is picked up by a driverproviding the transport service. Each time the user specifies alocation, the service application running on the user's client device170 provides the corresponding location data point 171 to the system 100so that a corresponding address or location information can bedetermined by the system 100 and provided to the service application.According to one example, the location data point 171 can be provided,by the service application to the system 100, as part of a request for acorresponding address. In this manner, the user can view and verify thatthe particular address is the address in which the user wants to bepicked up at for transport service (or dropped off at, in anotherexample).

The location determination 110 receives the location data point 171 fromthe client device 170 and in response, can perform a reverse geocodingprocess for that location data point 171. In one example, the locationdetermination 110 can perform the reverse geocoding process bydetermining, based on one or more conditions, which resource (e.g.,which particular database, which third party reverse geocoding service,etc.) to use to translate the location data point 171 to a correspondingaddress (e.g., a street address) or to a corresponding location name,information, or identifier. In some examples, the location determination110 includes a resource selection and a language match.

The location determination 110 can access or communicate with aplurality of resources to determine location information or an addressfor a received location data point 171. The plurality of resources caninclude the geofence database 150, the map database 160, a plurality ofthird-party reverse geocoding services 190, and/or other databases, suchas a database for storing text strings, not illustrated in FIG. 1.Depending on implementation, the geofence database 150 and/or the mapdatabase 160 can be included with the system 100 and/or maintained byadministrator user(s) of the system 100.

According to an example, the geofence database 150 is a database thatstores a plurality of user-created or user-configured geofences (e.g., apredefined region defined by three or more location data points) eachcorresponding to a descriptive text string. Each entry in the geofencedatabase 150 can include (i) a plurality of location points that definethe boundary of the geofence and (ii) location information (e.g., as aspecified text string) corresponding to the geofence. For example, ageofence can be created for a geographic region, such as an area near anexit or door (e.g., near the pick-up area) of Terminal 2 of SanFrancisco International Airport, and identified as “Terminal 2, SFO.” Insome examples, a geofence entry can also include a time period (e.g., astart date, a start time, an end date, an end time, etc.) for thatgeofence entry. An administrator can interact with a geofence interface155 via one or more inputs 157 to create, edit, and/or delete geofencesin the geofence database 150.

The map database 160 can correspond to mapping information stored withthe system 100. For example, the mapping information can be provided byor retrieved from mapping sources, such as OpenStreetMap (OSM), an opensource mapping database, or from other mapping sources. The map database160 can be periodically updated using information from OSM and/or can beupdated by an administrator of the system 100 (e.g., the system 100stores and maintains the map database 160). The location determination110 can access the geofence database 150 and/or the map database 160 todetermine location information corresponding to the received locationdata point 171.

In addition, the system 100 can also access one or more third-partyreverse geocoding services 190 over a network via one or more serviceinterfaces 140. A third-party reverse geocoding service provides atranslation of a location data point, such as a latitude and longitude,to a readable address or name. A plurality of different third-partyreverse geocoding services 190 can exist and be available to the system100 (e.g., via the service interface 140). For example, a third-partyreverse geocoding service 190 can provide street addresses for locationdata points that are within a particular region, such as a large city orcountry (e.g., a third-party reverse geocoding service can specialize intranslating location points in South Korea), while another third-partyreverse geocoding service 190 can provide street addresses for locationpoints that are within another region (e.g., France). In anotherexample, a third-party reverse geocoding service 190 can be moreencompassing than others (i.e., have a larger database of addresses thatspan a larger geographic region than others, such as Google Inc.'sreverse geocoding service).

Based on the received location data point 171 and one or more conditionsof the system 100, the resource selection can determine which resourceto use to determine the location information or address for the receivedlocation data point 171. For example, the resource selection can beconfigured, via one or more parameters inputted by the user of thesystem 100, to determine which resource to use first, then second ifnecessary, then third if necessary, and so forth, in order to determinethe location information or address for the received location data point171. In addition, in one example, the location determination 110 canfirst determine whether the error value received with the location datapoint 171 is equal to or greater than a threshold error value. An errorvalue that is equal to greater than the threshold error value canindicate that the latitude and longitude determined by the GPS componentof the client device 170, for example, has a high likelihood of beingfaulty or inaccurate.

If the location determination 110 determines that the error value isequal to or greater than a threshold error value, for example, theresource selection can select a text string database (not shown inFIG. 1) as the resource for the location determination 110 to access.The location determination 110 can retrieve from the text stringdatabase a default text string and provide the default text string tothe client device 170 (that transmitted the location data point 171)indicating to the user that the location could not be determined or thatthe GPS component provided inaccurate location data. In other examples,the text string can also prompt the user to try again or select a newlocation. In such an example, because the error value is determined tobe high, the location determination 110 can forego using a third-partyreverse geocoding service 190, thereby reducing network bandwidth useand reducing the number of communications made to third-party reversegeocoding services 190, and in general, does not perform a reversegeocoding process to determine a corresponding address or locationinformation for the received location data point 171.

As an addition or an alternative, in some examples, the resourceselection can also store a ranking of the resources (relative to eachother) to use to determine an address or location information for acorresponding received location data point 171. In one example, theresources can be previously categorized or ranked relative to each otherby an administrator of the system 100. When the location determination110 receives a location data point 171, the resource selection canselect the highest ranked resource that is available or accessible touse to determine the corresponding address or location information. Forexample, the ranking of the resources to be used by the locationdetermination 110 can be prioritized in this order: (1) the geofencedatabase 150, (2) a location-specific third-party reverse geocodingservice(s) 190, (3) a larger, more-generic third-party reverse geocodingservice 190 (as compared to the location-specific third-party reversegeocoding service(s)), (4) the map database 160, and (5) text stringdatabase. The order of the resources can be different in other examples.In some examples, the administrator can adjust the rankings of theresources for the resource selection of the location determination 110.

When the location determination 110 receives the location data point171, it can perform a reverse geocoding process to determine thecorresponding address or location information. The reverse geocodingprocess includes determining which resource to use to determine thecorresponding address or location information for the received locationdata point 171. In one example, the resource selection can determinethat the geofence database 150 is to be used first (e.g., based on theabove-mentioned ranking). The location determination 110 will access thegeofence database 150 to determine whether the location data point 171is located within a predefined region of a geofence (e.g., within aboundary defined by three or more location points for the geofence). Ifthe location data point 171 is within a predefined region of a geofence,the location determination 110 identifies the corresponding locationinformation 151 or descriptive text string from the geofence database150 and provides the location information 151 or descriptive text stringas location information 173 to the client device 170 via the deviceinterface 130.

As discussed, a geofence entry that is stored in the geofence database150 can be a time-based geofence entry, in which one or more durationsof time is associated with that geofence entry. A duration of time canindicate when the geofence is “active.” For example, a geofence canspecify a duration of time in which an event (e.g., a concert, asporting event, a parade, etc.) may occur. Such a time-based geofencecan indicate descriptive text string corresponding to such an event whenthe user requests a pickup location in the geofence region during thatduration of time. If the location determination 110 receives a locationdata point 171 that is within the predefined region of a time-basedgeofence, but is received a particular instance in time that is notduring the specified duration of time of that geofence, the locationdetermination 110 can indicate that the location data point 171 does notmatch an existing geofence entry in the geofence database 150 (e.g.,even though the location data point 171 is within a predefined region ofa time-based geofence). The resource selection can determine thatanother resource is to be used for the reverse geocoding process basedon the specified order or hierarchy.

If the location data point 171 is not within a predefined region of anyof the geofences in the geofence database 150, the resource selectioncan determine if a location-specific third-party geocoding service 190corresponding to the location data point 171 is accessible. In somecases, a third-party reverse geocoding service may be inaccessible as aresult of access limits (e.g., only a certain number of reversegeocoding requests can be made per second, such as a queries per second(QPS) limit), bandwidth limits, hardware problems (e.g., the third-partyreverse geocoding service server is down or has network problems), etc.In addition, the location data point 171 can be within an area where nolocation-specific third-party geocoding service 190 is available. If alocation-specific third-party geocoding service 190 is accessible (e.g.,such as a location-specific third-party geocoding service 190 that isspecific to a city, region, state, or country, etc., that the locationdata point 171 is located in), the location determination 110 can send areverse geocode request 111 (e.g., query the location-specificthird-party geocoding service 190) using the location data point 171 toa location-specific third-party geocoding service 190 that can providethe translation from the location data point 171 to a correspondingaddress. Once the location determination 110 receives the correspondingaddress 191 from the third-party reverse geocoding service 190, thelocation determination 110 can provide the address 173 to the clientdevice 170.

On the other hand, if no location-specific third-party geocoding service190 is accessible, the resource selection can determine if a larger,more-generic third-party reverse geocoding service 190 (as compared tothe location-specific third-party reverse geocoding service(s)) isaccessible. In some examples, the larger, more-generic third-partyreverse geocoding service 190 can encompass a larger geography of datapoints (e.g., such as the reverse geocoding service provided by GoogleInc.). If the larger, more-generic third-party reverse geocoding service190 is accessible, the location determination 110 can send a reversegeocode request 111 (e.g., query the larger, more-generic third-partygeocoding service 190) using the location data point 171 to a larger,more-generic third-party geocoding service 190 that can provide thetranslation from the location data point 171 to a corresponding address.Once the location determination 110 receives the corresponding address191 from the larger, more-generic third-party reverse geocoding service190, the location determination 110 can provide the address 173 to theclient device 170.

If no third-party geocoding service 190 is accessible, the resourceselection can determine if an internal map database 160 of the system100 is accessible. The map database 160 can correspond to mappinginformation provided by or retrieved from one or more mapping sources.If the map database 160 is accessible, the location determination 110can perform a lookup of the location data point 171 in the map database160. If the location data point 171 has a corresponding address orlocation information 161, the location determination 110 can provide theaddress or location information 161 as location information 173 to theclient device 170 via the device interface 130.

If the map database 160 is inaccessible or unavailable or if nocorresponding address or location information is found in the mapdatabase 160, the resource selection can determine that no resources areavailable or accessible and the location determination 110 can identifya custom text string that is stored in the text string database. Thelocation determination 110 can cause the custom text string, such as“Address is unavailable,” “Select another location,” or “Input anaddress in the text field,” to be transmitted to the client device 170via the device interface 130. In this manner, the user can receiveaccurate information regarding an address or location for an on-demandlocation-based service before making a request for the service.

According to some examples, the location determination 110 can alsodetermine the preferred language of the user operating the client device170. For example, the system 100 can maintain a profile database ofusers and/or the users' respective client devices 170. The system 100can also maintain a profile database of drivers. A profile of a user caninclude a user identifier (ID) (e.g., a user name, email address, etc.)and a preferred language (e.g., English, Korean, Arabic, French,Chinese, etc.) along with other user information. When a user operatesthe client device 170 and the client device 170 provides a location datapoint 171 to the location determination 110 (e.g., along with the userID), the language match can identify the preferred language of that userby accessing the user's profile from the profile database of users. Inthis manner, when a corresponding address or location information 173 isto be provided to the client device 170 of the user for the locationdata point 171 selected by that user, the location determination 110 cantransmit the address or location information 173 in the preferredlanguage of that user.

According to variations, the location determination 110 (e.g., via thelanguage match) can provide the address or location information 173 in apreferred language of a corresponding user and/or user's client device170 by (i) performing a translation of an address or locationinformation that is determined using the reverse geocoding process(e.g., determined using one of the plurality of resources), (ii)accessing a third-party translation service to perform the translationof the determined address or location information, and/or (iii) duringthe reverse geocoding process, cause the location determination 110 tomake the reverse geocoding request 111 to a third-party reversegeocoding service for the address 191 in the specified preferredlanguage. In some examples, the translation can be a translation fromone language (e.g., English) to another language that is expressedphonetically (e.g., phonetically in Chinese).

The system 100 can also operate with or as part of another system thatenables location-based services to be arranged between parties. Forexample, the system 100 can include a transport arrangement 120 thatreceives a transport request 175 from a client device 170. A user of theclient device 170 can select a location, such as a location for pick-up,and receive an address or location information 173 from system 100. Theuser can then make a transport request 175 via the service applicationoperating on the client device 170 to system 100 using the selectedlocation (or select a different location). The transport request 175 caninclude the location data point 171 and the transport arrangement 120can arrange for transport to be provided by a driver based on thelocation data point 171, which specifies the pickup location. Forexample, a plurality of drivers can operate a plurality of driverdevices 180. The transport arrangement 120 can select a driver based onthe transport request 175 (e.g., what type of vehicle is requested, whattime, the user's ratings, the driver's ratings, etc.) and/or thelocation data point 171 (e.g., the transport arrangement 120 can selecta driver that is nearby as compared to other drivers who are furtheraway).

When the transport arrangement 120 selects a driver, information 125about the transport service can be provided to the client device 170 andthe driver device 180 of the selected driver (e.g., to the serviceapplications operating on the respective devices). The driver is alsonotified of the pickup location selected by the customer. Instead ofproviding a location data point 171 selected by the user of the clientdevice 170 to the driver device 180, however, in some examples, thelocation determination 110 can provide the corresponding street addressor location information (previously determined for the user of theclient device 170) to the driver device 180 as address or locationinformation 183.

According to some examples, the location determination 110 can alsodetermine the preferred language of the selected driver. When a driveris selected by the transport arrangement 120, the language match of thelocation determination 110 can identify the preferred language of theselected driver by accessing the driver profiles in the profile databaseof drivers (e.g., using a driver ID). The language match can compare thepreferred language of the user and the preferred language of theselected driver to determine if they are the same. If the preferredlanguages match, the location determination 110 does not have to performanother translation step, but instead transmit the determined address orlocation information (that was previously transmitted to the user'sclient device 170) to the driver device 180. On the other hand, if thepreferred languages do not match, the location determination 110 canperform the reverse geocoding process again (e.g., to receive an address193 in the preferred language of the driver) and/or perform atranslation of the determined address in the preferred language of theuser to the preferred language of the driver.

In this manner, the system 100 provides many benefits in providinglocation information or street addresses using a predefined reversegeocoding process. For example, if a third-party reverse geocodingservice is unavailable or inaccessible, the system 100 can still providerelevant location information to the user of the client device 170 usingother resources. Administrators of the system 100 can continue to updateinternal databases, such as the geofence database 150, to provide moregranular and time-based location information messages to users. Suchgranular and time-based information may be more useful to a user as wellas a service provider then a typical street address when roads, streetcorners, regions, etc., are blocked or closed due to temporary events(e.g., marathons or city festivals). In addition, because the system 100provides the determined address or location information to both theclient device and the driver device for purposes of an on-demandservice, the user and the selected driver can receive the sameinformation without having two separate reverse geocoding requests bemade to a third-party reverse geocoding service (i.e., individually madeby the client device and the driver device).

Methodology

FIGS. 2A and 2B illustrate example methods for determining locationinformation, according to an embodiment. Methods such as described byexamples of FIGS. 2A and 2B can be implemented using, for example,components described with an embodiment of FIG. 1. Accordingly,references made to elements of FIG. 1 are for purposes of illustrating asuitable element or component for performing a step or sub-step beingdescribed.

Referring to FIG. 2A, the system 100 can receive a location data point,such as a GPS data point, from a client device over one or more networks(205). In some examples, the location data point can comprise alatitude, a longitude, and an error value. If the error value is lessthan a threshold error value, the system 100 can perform a reversegeocoding process (210-250) for the received location data point. Anexample of the reverse geocoding process, such as performed by thelocation determination 110 of FIG. 1, is described in detail.

The location determination 110 determines if the location data point iswithin a predefined region of a plurality of predefined regions thathave been configured by an administrator of the system 100 (210). If thelocation data point is within a predefined region, the locationdetermination 110 identifies location information corresponding to thatpredefined region, and transmits the location information to the clientdevice (215). Information about the plurality of predefined regions canbe stored in a geofence database as geofence entries. In some examples,a geofence entry can be timed-based, and include a time period (e.g., astart date, a start time, an end date, an end time, etc.) for thatgeofence entry. For example, a geofence entry can specify a region thatsurrounds and/or corresponds to AT&T Park, and have a time periodrelated to the date and a duration of a baseball game played there(e.g., one hour prior to the game to one hour after the game). Thecorresponding location information text string for the predefined regionof AT&T Park can recite, for example, “Giants game—walk to 3^(rd) St.and Brannan for pick-up.” The location information can be informative toguide the user to move to another location for pickup (e.g., such as fora transport service) because the actual address/location might becongested with people and/or roads may be closed. In this manner, such apre-configured location information provided to a user's client devicecan be more useful for the user for purposes of on-demand services.

If the location data point is not within a predefined region, thelocation determination 110 determines if there is an available oraccessible location-specific reverse geocoding service (220). Forexample, a third-party reverse geocoding service may be unavailable if arate limit, such as the number of queries per second (QPS) has beenreached at the time the location data point is received from the clientdevice. In another example, a third-party reverse geocoding service maybe unavailable if a call is made to the third-party reverse geocodingservice, and no address is received in response to the call (e.g., dueto computing resources of the third-party reverse geocoding servicehaving failed or crashed, or if network connectivity to the third-partyreverse geocoding service has been lost).

If a location-specific third-party reverse geocoding service isaccessible for translating the location data point to an address, thelocation determination 110 can transmit a request to thelocation-specific third-party reverse geocoding service (225). Therequest can include the location data point. In one embodiment, therequest can also be made for a street address in a preferred language ofthe user. The location-specific third-party reverse geocoding servicecan translate the location data point to a street address and providethe address to the location determination 110. The locationdetermination can transmit the address to the client device (228). Inone variation, if the location-specific third-party reverse geocodingservice is unable to provide an address for the location data point, thelocation determination 110 can determine if there are other third-partyreverse geocoding services that are available or accessible forproviding the translation. If no third-party reverse geocoding servicesare available or accessible, the location determination 110 can useother resources, such as the map database of the system 100 to determinelocation information or provide a custom text string to the clientdevice.

Referring back to 220, if location-specific third-party reversegeocoding services are unavailable or inaccessible for translating thelocation data point to an address, the location determination 110 candetermine if a larger, more-generic third-party reverse geocodingservice (as compared to the location-specific third-party reversegeocoding service) is accessible (e.g., such as the reverse geocodingservice provided by Google Inc.) (230). If a larger, more-genericthird-party reverse geocoding service is accessible, the locationdetermination 110 transmits a request to that location-specificthird-party reverse geocoding service (235). The location determination110 can receive the translated address and transmit the address to theclient device (238).

In some cases, third-party reverse geocoding services may not beavailable for or accessible by the system 100. If no third-party reversegeocoding services are accessible or available, the locationdetermination 110 can determine if a map database of the system 100(e.g., an internal database maintained by the system 100) is availablefor translating the location data point to the address (240). If the mapdatabase is available, the location determination 110 can retrieve astored address or location information from the map database using thelocation data point and transmit the retrieved address to the clientdevice (245). If the map database is unavailable (or if no address isfound that corresponds to the location data point), the system 100 canidentify a specified text string to be transmitted to the client device(250) (e.g., “Address is unavailable,” “Select another location,” “Callyour driver”).

While FIG. 2A has been described in a specific order in which thelocation determination 110 accesses or attempts to access a plurality ofresources, depending on variations, other orders or rankings ofresources are possible. In other examples, the location determination110 may not access or attempt to access certain resources. For example,when a total QPS limit has been reached for a third-party reversegeocoding service, the location determination 110 may not access thethird-party geocoding service, and instead, access another resource(e.g., the map database of the system 100) or other internal databases.In addition, different resources may be available for differentgeographic regions in which the location data point is located in.

For example, FIG. 2B illustrates another example for determininglocation information, according to an embodiment. FIG. 2B is similar toFIG. 2A except that in FIG. 2B, the location determination 110 does notindividually access or attempt to access a location-specific third-partyreverse geocoding service. The location determination 110 receives alocation data point from a client device (255) and determines if thelocation data point is within a predefined region (260). If yes, theidentified location information corresponding to the predefined regionis transmitted to the client device (265).

If the location data point is not within a predefined region, thelocation determination 110 determines if a third-party reverse geocodingservice is available or accessible (270). If a third-party reversegeocoding service is available or accessible, the location determination110 transmits a request to the service (275). The third-party reversegeocoding service can perform a translation of the location data pointto an address, such as a street address, and return a result to thelocation determination 110. The location determination 110 can transmitthe address to the client device (278).

If no third-party reverse geocoding service is available or accessible,the location determination 110 determines if the map database of thesystem 100 is available (280). If yes, the location information oraddress corresponding to the location data point is retrieved from themap database and transmitted to the client device (285). If the mapdatabase of the system 100 is unavailable, the location determination110 can identify a custom text string to transmit to the client device(290).

FIG. 3 illustrates an example method for determining locationinformation, according to another embodiment. A method such as describedby an example of FIG. 3 can be implemented using, for example,components described with an embodiment of FIG. 1. Accordingly,references made to elements of FIG. 1 are for purposes of illustrating asuitable element or component for performing a step or sub-step beingdescribed.

The system 100 can receive a location data point from a client device(310). The client device can run a service application, for example, inwhich a user of the client device can specify a location for use with anon-demand or location-based service. In one example, the serviceapplication can provide a map interface in which a user can select thelocation by moving a graphic feature on the map interface. The selectedlocation can correspond to a location data point, such as a latitude anda longitude.

In response to receiving the location data point, the locationdetermination 110 performs a reverse geocoding process to determine theaddress or location information corresponding to the received locationdata point (320). In some examples, the reverse geocoding process cancorrespond to steps 210-250 of FIG. 2A or steps 260-290 of FIG. 2B. Thelocation determination 110 provides the result of the reverse geocodingprocess, e.g., an address, location information, or custom text string,to the client device. The user can also continue to change the locationon the map interface before he or she make a transport request or insome embodiments, can change the location even after the transportrequest is made (but before a predetermined time before the estimatedtime of arrival by a driver). The location determination 110 cancontinue to perform the reverse geocoding process (320) each time theclient device provides a different location data point to the system 100(e.g., each time the user moves the graphic feature on the map interfaceof the service application).

In some examples, the user can make an on-demand service request to thesystem 100 (e.g., a delivery request, an entertainment service request,a transport request, etc.) via the client device using the location datapoint (330). The system 100 can arrange for the on-demand service to beprovided for the user by a service provider. For example, the system 100can use information about the transport service request, informationabout the user, and information about available drivers in a geographicregion corresponding to the location data point to select a driver toprovide the transport service (340). In other on-demand serviceexamples, the system 100 can select a particular driver for performing adelivery service, select a food vendor for providing a food service,etc. Information about the transport service can be provided to both theclient device of the user and the driver device of the driver.

For example, for a transport service, a driver should know the pick-uplocation specified by the user. The user specifies the pick-up locationand can receive the street address or location information identified bythe system 100 via the reverse geocoding process described in FIG. 2A or2B. Such information should also be provided to the driver. In oneembodiment, the location determination 110 can provide the address orlocation information to the user in a preferred language of the user.The location determination 110 can determine if the preferred languageof the user matches the preferred language of the driver (350). If thepreferred languages match, the location determination 110 can transmitthe already determined address or location information to the device ofthe driver (355).

On the other hand, if the preferred language of the user does not matchthe preferred language of the driver, the location determination 110 can(i) perform a translation of the determined address or locationinformation, (ii) access a third-party translation service to performthe translation of the determined address or location information,and/or (iii) perform the reverse geocoding process a second time, whichcan include making the reverse geocoding request to a third-partyreverse geocoding service for an address or location information in thepreferred language of the driver (360). The address or locationinformation that is in the preferred language of the driver can beprovided to the device of the driver (370).
